Yep, that's the number SeekingArrangement.com came up with in its survey of about 18,000 men and women. The site—known for matching up women with its roster of "Sugar Daddies"—asked guys to tally up the amount they typically spend on V-Day gifts.

The results? Single dudes spend about $257 on a date (not the ones we've dated, but...), while those in committed and married relationships spend $180 and $203, respectively.

That means the average guy has to shell out an average of $218 "for a happy ending to their night."

Gross.

These dudes have it all wrong if they think cash=sex on Valentine's Day. Sure, it's likely that every guy has V-day sex on his mind when he heads out on a date, but to expect it? Bad form.

Oh, and if he pressures you to have sex because he dropped a few dollars on dinner? Do it if you want to, otherwise ditch him, stat.
